Abstract

The utility model belongs to a device for sucking and exhausting fumes, which is a chest type cooker hood which is composed of a chest body installed on a stove and an exhaust pipe communicated with the chest body and a window. The utility model utilizes a conventional exhaust fan in the exhaust pipe to suck and exhaust fumes gathered in the chest body. The chest type cooker hood not only strengthens the fume exhausting effect, but also has a combustion promoting and a gas discharging actions for coal-combustion stoves, and is a fume exhausting device with simple structure, easy installation and low cost.

Description

Chest cooker hood

The utility model belongs to the device of suction discharging flue gas, is a kind of box oil-fume extractor.

At present, be used for the smoke exhaust in kitchen or the window place that ventilating fan is installed in kitchen range top or kitchen, the oil smoke that kitchen range are dispersed in the kitchen aspirates discharging, because the scattered band of flue gas affects their suction emission effects to flue gas more to some extent, though smoke exhaust is nearer apart from kitchen range, suction discharging effect is stronger, but its working condition still is an open type.

The purpose of this utility model is to provide a kind of box oil-fume extractor, it is particularly suitable for device on the kitchen range of laying near the window, this oil-fume extractor can accumulate in flue gas in the casing, by the flue gas in the conventional ventilating fan suction discharging casing in the blast pipe, to overcome the existing in prior technology deficiency.

Overall structure of the present utility model is:

Casing (6) device is on the kitchen range frame, blast pipe (1) is connected between casing rear wall (7) and the window, ventilating fan (9) is installed in casing rear wall top, and be positioned at the port of blast pipe, rear wall door (3) upper edge of capping blast pipe port adopts bearing pin to connect with casing (6) top (2), and casing Qianmen (4), (5) connect with box bilateral wall or upper and lower wall bearing pin.

Its design feature also has:

Upper and lower or left and right two fan (4), (5) are divided at the Qianmen of casing, connect with upper and lower wall of casing or two side bearing pin respectively, casing first half two side (8) is the printing opacity baffle plate, and the two side of casing Lower Half and rear wall (7) are surrounded by metallic plate, and lighting also is housed in casing.

Accompanying drawing of the present utility model has:

Fig. 1 is the side-looking structure diagram of box oil-fume extractor.

Fig. 2 is that the master of box mist extractor looks sketch.

Fig. 3 is a rear wall structure schematic diagram in the casing.

Accompanying drawing has provided embodiment of the present utility model, further specifies as follows in conjunction with the accompanying drawings:

This oil-fume extractor is particularly suitable for device on the fire coal or gas kitchen ranges laid near window, blast pipe (1) two ends that are about 200-300mm connect with window and casing top respectively, conventional 9 " or 12 " ventilating fans (9) (as shown in Figure 3) are installed in blast pipe port at the casing rear wall, rear wall door (3) is in casing, and and the top bearing pin connect, at any time folding, capping exhaust duct port or make blast pipe and casing UNICOM, the casing Qianmen is divided into upper and lower two fans to make things convenient for cooking operation.Plastics or other transparent material plates are adopted in wall box top, are beneficial to daylighting.

When carrying out cooking operation, to open two fan Qianmens, and raise and hang up rear wall door (3), behind the connection power supply, the ventilating fan of rotation can aspirate the oil smoke gas that is dispersed in the casing, outside the emission by exhaust pipe exit window.Use coal-fired kitchen range, need not when fire, can open rear wall door (3), only close the Qianmen with coal gas in the discharging case.With connecting power supply before the fire, because the swabbing action of ventilating fan can be fired prosperous stove fire at short notice.

The obtained technological progress of the utility model is:

This casing oil-fume extractor is that the flue gas that combustion gas or coal-fired cooking utensils distribute is gathered in the casing, and aspirate discharging by the conventional ventilating fan in the blast pipe of UNICOM's casing and window, not only changed the mode of conventional smoke exhaust discharging flue gas, strengthened the emission effect of flue gas, and coal-fired cooking utensils had concurrently short combustion and the coal gas effect of releasing, be a kind of simple in structure, be easy to lower-cost oil-fume extractor is installed.

Claims
